The reason why you don’t see many people venturing into trading most especially the future trading is the fact that it actually needs two things. One is the substantial knowledge on technical analysis and fundamental analysis, and the other is capital. Trading is regarded as gambling by some and for you to earn from it you have to have your own capital to start off.

Initially the objective of everyone who is into cryptocurrency investment is to make profit, and in normal circumstances their is some certain things you need to involve yourself into and thing's you don't need to involve yourself when you know that have not understand the full concepts or theories of it, basically, trading involves skills and when you have not acclimatise with its protocols you will not be successful, its not only the capital that's is setback to whosoever that wants to venture into it, some have already know the implications of trading when you have not understand it's concepts and analysis before venturing into it.
